Re: Update 04-26-2011

I was told by the local dealer that these motors take something like 4-5 gallons to fill the block up. And it is only being filled up by a 1/2" hose. So it takes some time. I use the two sided water flow muffs. Bought them special for this motor.

Hell the honda kicker I only use a 5 gallon buck with the hose in it. lol

Ok direct answer to a direct question...4 to 6 degrees ATDC for idle timing.

Re: Update 04-26-2011

Thanks! Just to confirm. That is after Top Bead Center.

Also After I Have this set, timing at idle, do I advance the idle screw to the linkages to hit the 1200 rpm? Or should I be able to idle at 1200rpm without cracking the butterflies by just playing with the timing?

Re: Update 04-26-2011

Started it up again today and rechecked the idle timing. It is set to 5 atdc. I think I had it right all along. Just my tacometer on the boat is off I think. Need to check out getting anew one.

Also sitting here and over thinking things again, Seeing I am running a 1987 small bore loopwer ingition and carb system. Should I be woried that this is a big bore looper block? Should I check for something tomorrow when I am out breaking it in. How do I know If I am running too lean? Seeing this is a freash rebuild and new prop.

Ignition dont care about bore size but carbs do. Most of the 200/225 loopers were jetted in the mid 60's(62/64/). If your high speeds are 64's or bigger you should be fine..

Re: Update 04-26-2011

Well yesterday was the day. Sorry for not posting earlier but I was celebrating that my luck did not kick me in the balls again. It ran and ran great!

Had a few issues. Nothing big but some stuff needed attention and fixing/adjustments.

The fist thing that needed addressing was the two piece check valve goin from the bottom recirc line to the top of the block. The straight through one. It came apart whil driving. I found this out hafter driving for 15-20 minutes and stopped and shut it down. Could not get it started so took the hood off and had my buddy turn it over. Saw fuel spewing out of open fitting. The excess fuel is due to me choking the motor every time I try to start it. When its warn no choke needed. Still learning. how to use motor. any ways when I got back home I loctite super glue the fitting together. Wont come appart now.

The second issue was setting all the idle linkages again. The throttle cable jam nut loosened and through off all my idle adjustments. So had to go through all that again. But that was easy and what shake down cruises are for.

The third issue was one started bolt loosened off and let the start jam on forward. Another easy fix with a little loctite blue or 242.

The other bigger issue is the motor warms up to 180 when idling/driving up to 2500 rpm. After 2500 rpms the thermostats open up and the temps drop. I was thinking of checking the thermos and opening up the idle hole in them a bit to let more coolant through to lower the head temps. IS this a good fix? Have not done anything yet.

The prop was a bit over pitched. The motor struggled to get up on plane. Had to basically give it full throttle and it still struggled to get up on plane. After it was it topped out at 45mph but at 4600rpm. So I'm going to stop by the dealer and trade in the prop for another one. Any thoughts on the right pitch. The prop I have is 14.3x21P.

Still clearing my throat of all the 2 stroke oil in the back of it. Running this double oil for breakin is going to get old real quick.

A couple of things I noticed that I have questions is one being shifting into gear. Do these motors allways sound a bit rough, gears clashing, when shifting? How would I know if my shift interupter switch is working? It does not sound that bad. But its not a syncronized gear transmission for sure.

The other thing with this motor that I have to ask about is how loud is the rotating assembly . There is something that is ringing running. It might have been the starter and that bolt. Just wondering.

But to summerize this thing ran great. Strong and fast but with a few minor little issues that need clearing up before fishing season. Thanks for all the help from everyone that gave input. It helped made my day very enjoyable and memorable yesterday. Thanks!!!

Re: Update 04-26-2011

Congratulations you did it, Keep an eye on that high temperature its very high in my opinion, break her in with the t-stats is what I will recommend unless you get it fix fast.
Hot=lean ..Yes even on Outboards
Remember to pull, photo and label your plugs through the break-in until you are 100 percent sure you are jetted correctly. The plugs are your first indication of any lean condition or rich ...
The reason to label and photo the plugs is simple you have a record, if one carb decides to quit you nip it before a major issue.
Good luck and post pictures of the Boat also you did an excellent job on this board sharing your experience with us all. I personally will take this moment to thank you and the many others who takes the time to this. God Bless ..

Re: Update 04-26-2011

Thanks man. I have pulled the plugs and they where still silver except where the trode's are. They (trodes) where just starting to turn black. So I think everything is ok.

The temp was 160 at idle and rose to 180 as the rpm's rose. When I hit 2500 rpm's the t-stats must have opened because the temp drop'd to 160'f every time. So I'm going to have a look at the t-stats again to see what can be done. But is there any fixes to this rework for make it work correctly?

Re: Update 04-26-2011

Forgive me if you know this already but you need quick firm shifts. You will do this motor NO favors if you ease it into gear.

 

[j_k_bisson]

Re: Update 04-26-2011

Re: Update 04-26-2011

Ok di not know that. Thanks I was easing it into gear. On my old force that is what you did. Plus I was worried about gunning it when shifting. I noticed that is does not jump when the shifter move slightly past the shift point.

Thanks for this tip.

Re: Update 04-26-2011

Oh yeah that was def your issue then. Dog clutches don't "mesh". Quick thunk and you're in. They'll make a racket if you ease it.

Re: Update 04-26-2011

Hey Jeff, dump that power boost cooling feature and update it. Replace & install the covers and springs off a 1986 70hp to the cylinder heads. The reason you see such a high temp is these heads run nearly dry(outer jacket) till boost pressure is changed and t-stat/poppet(serves 2 purposes)is blown off seat.

 

[j_k_bisson]

Re: Update 04-26-2011

Re: Update 04-26-2011

My motor has had the covers and springs replaced by someone else before. I will replce the springs right away though to make sure they are the right ones though. Is there supossed to be a by pass hole to allow a bit of water to pass into the heads in the thermostats? sort of like a car?

Re: Update 04-26-2011

Re: Update 04-26-2011

If you t-stat/poppet housings are white,replace them with the black ones.

 

[j_k_bisson]

Re: Update 04-26-2011

Re: Update 04-26-2011

I did replace them with the black ones. Is there an issue with modifying the springs. My local dealer stated that they had tried this rework and had issues with it. Just wondering if this is normal temps at idle with this rework? 160-180'F

Re: Update 04-26-2011

Re: Update 04-26-2011

Well stopped at the local dealer yesterday and picked up a different new prop. A 14.3x17". Just got back and the prop feels right. A bit to get up on plane but nothing to complain about. Just need to figure out triming the motor and trim tabs. Also it topped out at 45.7mph on gps at 5600 rpms. SO the prop worked out great. Now I have a bit of a chug in the rpm range of 1200 to 2000rpm's. At 2000 rpms the boat is not up on plane but the nose is up in the air like it is trying to get up there. You need to rev to be at 3000 to get it up on plane.

It seams to be either loading up with fuel or a power pac is going. I did a compression check when I got back and they are all 1 to 2 psi different from each other. Tonight I am going to change out the power packs witha new set I have. Still running the old ones.

My question is how do I find out if it is loading up with fuel at the rpm range I am experiencing?

NICE!

Are you punching it to get up on plane and then backing off? or are you easing it up through the throttle range? Cuz that will take a while.

Re: Update 04-26-2011

Re: Update 04-26-2011

what main jets did you put in it?

 

[j_k_bisson]

Re: Update 04-26-2011

Re: Update 04-26-2011

Yep I am punching it to get up on plane faster. then easing it off and triming it at the rpms good north.

As to the main jets, they where 14,50,62d's. After reading the service manual It states that a pinched recirc line could cause this possibly. I know I have a partially pinched line behind the starter. I'm going to replace this one with a new piece of hose that is longer than the rest but crosses lower than the starter body.

Could this be my problem?

Also reading on the manual they said at 900 rpms the block temp should be 140'f +/- 15'f. At this rtpm I'm 170'f. At 1500-2000 rpm I'm at 180-186'f. Remember that I have that converted t-stat system. Yes it is the black t-stats. Could this alos be the problem?

Lastly I changed out the power packs with new one tonight. Just incase this was the issue. The kicks where only after a half hour of driving that it started doing it. Fresh off the trailer id did not do it. So That possibly could be it as well.

Give me your thoughts of things I should check out.
